b18b head on b20 bottom end, better then b20 head?
herd that the b18 head on a b20 bottom would raise compression .1 and flow better, and that the cams are a little meanier. anybody know for sure. i assumed that the 2 heads might be identicle, but you never know. of course vtec will come later... justin, thanks

pretty much. i forget what head it is, but there is a b20 with bseries vtec sized valves in it stock, that would be a good route to go.

yes it is better becouse the b20 is made for a suv and the b18 head revs higher
becouse of the cams

but you can also keep the b20 head on it and put the b18 cams in that head and it revs alot faster
ive tried it both ways on my b20 block
